As Scientists Were Unraveling the Mysteries Associated with Transcription and Translation

question 4

Multiple Choice

As scientists were unraveling the mysteries associated with transcription and translation in eukaryotes, they discovered there was not a one-to-one correspondence between the nucleotide sequence of a gene and the base sequence of the mRNA it codes for. They proposed the genes-in-pieces hypothesis. How can the genes-in-pieces hypothesis be explained?

• A) Introns are noncoding segments of DNA that are present in the initial transcript, but are removed by splicing.
• B) Introns are noncoding segments of DNA that are not read or transcribed by RNA polymerase II.
• C) Exons are noncoding segments of DNA that are not read or transcribed by RNA polymerase II.
• D) Exons are noncoding segments of DNA that are present in the initial transcript but are removed by splicing.
